Spark Plugs

Turner Motorsport insists on Genuine BMW or Bosch OEM or NGK OEM spark plugs in all of our work and maintenance packages. Bosch and NGK are original suppliers to BMW for spark plugs and the ignition system is set up to use these plugs. To keep the engine running at its best, and get the most from your performance upgrades, we only recommend direct replacement spark plugs. We also sell helpful tools and accessories for changing out spark plugs. Some engines require special tools for replacing spark plugs.

Dinan Iridium Spark Plugs are an excellent upgrade for tuned, and even stock engines. Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs. Dinan spark plugs are great for high boost, high cylinder pressure, high cylinder temperatures, and high-power situations, and they pair nicely with a set of Dinan ignition coils, where applicable. However, they are not only for tuned and higher output vehicles that may benefit from a plug cooler than the factory heat range - they also are applicable to non-tuned / stock vehicles as well! The D640-0003 spark plug applies to the following engines: B48 TU B58 TU2 (Gen 2 B48 Gen 3 B58)
